[1] Hogyŏng, who called himself General Seonggol, came from Mount Baekdu and traveled far and wide, finally settling down in Songak (modern Kaesong) and starting a family.
[2] Gang Chung, a son of Hogyŏng, planted pine trees on Mount Songak so that rocks wouldn't be visible in order to fulfill a prophecy, based on feng shui, that his descendant would unite the "Sam Han" (삼한; 三韓),[2] another name for the Three Kingdoms of Korea.
[5] After reaching adulthood, Chakchegŏn, who was described as courageous and exceptionally intelligent, set sail for Tang to meet his father Emperor Suzong.
However, he was caught in a storm in the middle of the Yellow Sea and encountered a dragon woman (용녀; 龍女) whom he brought back home and married.
[12] The Encyclopedia of Korean Culture interprets Chakchegŏn being the son of Emperor Suzong of the Tang dynasty as a hagiography and his marriage to the dragon woman from the Yellow Sea as symbolic of the maritime influence of Wang Kŏn's ancestors, who engaged in trade with China for generations.
